PHILIPS
The foundations for what was to become one of the world's biggest
electronics companies were laid in 1891 when Gerard Philips established
a company in Eindhoven, the Netherlands, to 'manufacture incandescent
lamps and other electrical products'.
The company initially concentrated on making carbon-filament lamps and
by the turn of the century was one of the largest producers in Europe.
Developments in new lighting technologies fueled a steady program of
expansion, and, in 1914, it established a research laboratory to study
physical and chemical phenomena, so as to further stimulate product
innovation.
Marketing companies had already been established in the US and France
before the First World War, and in Belgium in 1919, and the 1920s saw an
explosion in their number.
It was at this time that Philips began to protect its innovations with
patents, for areas taking in X-ray radiation and radio reception. This
marked the beginning of the diversification of its product range. Having
introduced a medical X-ray tube in 1918, Philips then became involved in
the first experiments in television in 1925. It began producing radios
in 1927 and had sold one million by 1932. One year later, it produced
its 100-millionth radio valve, and also started production of medical
X-ray equipment in the United States.
